Joke found in Colorado Springs on the "Bon Ton" restaurant menu:

Early one morning, a mother went in to wake up her son.
"Wake up, son, it's time to go to school."
"But why, mom? I don't want to go."
"Give me two reasons why you don't want to go."
"The kids hate me, one. And the teachers hate me, two."
"That's no reason not to go to school. Come on, now. Get ready."
"Give me two reasons why I should go to school."
Well, for one, you're 52 years old.
For another, you're the school principal.
